Blank for multi-compartmented containers



United States Patent 3,135,454 BLANK FOR MULTI-CGMPARTMENTED CONTAINERS Glenn E. Struble, Hamilton, and Earl F. Borgernenke,

Cincinnati, Ohio, assignors to Diamond National Corporation, New York, N.Y., a corporation of Delaware Filed Sept. 13, 1962, Ser. No. 223,318 a 1 Claim. (Cl. 22927) This invention relates generally to containers and more particularly to an improved multi-compartmented container blank and method for assembling the same.

This application is a continuation-in-part of the application of Glenn E. Struble Ser. No. 115,415, filed June 7, 1961.

A primary object of the present invention is to provide a novel one-piece container blank which is readily produced and which includes panels which during assembly will dispose an intermediate, compartment-forming partition in its oriented position to form a multi-compartmented container.

Another object of the present invention is to provide a novel method for erecting a container blank which automatically orients a partition to form a multi-compartmented container.

A further object of the present invention is to provide a novel carton produced from a one-piece blank in which during assembly a partition panel is provided to form a multi-compartmented carton, and the partition panel prevents bulging of opposed side walls to which it is attached.

Other and more specific objects and the nature and advantages of the present invention will become apparent from a consideration of the specification when taken in conjunction with the accompanying drawing, in which:

FIG. 1 is a plan view of the blank of the invention, showing in phantom lines a glue strip area and cut line for forming partition-panel and container glue flaps;

FIG. 2 is an end elevation of the blank of FIG. 1 looking at the lower edge thereof, and showing in phantom lines means for applying a glue strip to one partitionpanel-glue flap;

FIG. 3 is a fragmentary plan view of the carton blank of FIG. 1 showing the first fold made during assembly of the container, and showing glue strips applied to opposite sides of the blank on the container glue flap and other partition panel glue flap;

FIG. 4 is an end elevation of FIG. 3 showing how the glue strips and a cut is made between the container glue flap and the glue flap of FIGS. 1 and 2;

FIG. 5 is an end elevation of the completely assembled container in its folded condition;

FIG. 6 is a view similar to FIG. 5 showing the assembled container partially erected; and

FIG. 7 is a top plan view of the erected container.

Referring to the drawings in detail in FIG. 1 a planar blank is indicated generally at 10, the blank being produced from a suitable paperboard material or the like by die cutting, for example.

The blank 10 includes two pairs of alternately disposed rectangular side wall panels 12, 14 and 16, 18 which are connected at the side edges thereof by mutually parallel fold lines 20, 22 and 24. The container to be produced from the blank of the exemplary embodiment will be relatively narrow in width, for example, the type used for pancake fiour, etc.

The sidewall panels 12, 14 and 16, 18 include at the upper and lower margins 26 and 28, respectively, pairs of upper closure flaps 30, 32 and 34, 36 and lower closure flaps 30, 32' and 34', 36.

The sidewall dimensions, it will'be understood by those skilled in the art, may be varied, i.e., the side walls may all be of the same area.

3,135,454 Patented June 2, 1964 "Ice which will be ultimately cut at line 42 to form adjacent side edges of a container glue flap 44 and a first partitionpanel glue-flap 46. The first pmtition panel glue-flap is foldably connected at its other side edge to a fold line 48; conveniently perforated if desired, to one side edge of a partition panel 50. The other side edge 52 of the partition panel 50 is connected by a fold line to a second partition panel glue flap 54.

The width A of the first pair of side wall panels 12, 14 is equal and the width 13 of the second pair of side wall panels 16, 18 is equal. The width B of the partition panel 50 is at least equal to that of the side wall panels 16 and 18. Further, the width C of the glue flaps 46, 54 is equal, accordingly the width D of the panel 40 is greater than the width C of glue flaps 46, 54 to form a width E of the container glue flap 44 after the glue flap 46 is formed. Although the disclosed embodiment shows glue 'flaps 46, 54 as being of equal width, it will be readily recognized by those skilled in the art that the widths of the glue fiaps may be different, the prime requisite being that they be wide enough to receive a glue strip and adhereto the opposed side walls.

The blank 10 is conveyed through suitable assembling apparatus, pertinent portions being shown diagrammatically in FIGS. 2 and 4. The inner surface of the blank 10 is shown in FIG. 1, and the blank is conveyed beneath a glue wheel 56 to apply on the inner surface of glue flap 46 a glue strip 58. The glue strip 58 will adhere at 60 on an intermediate portion of the side wall panel 14 when the first assembly fold is made at fold line 24; see FIGS. 2-4.

The first fold of the blank disposes, as seen in FIGS. 3 and 4, the side wall panel 18 in overlying relation to a portion of the side wall panel 14.

The blank 10 is conveyed beneath a combined cuttingand-glue-applying wheel 62 which forms the cut line 42 to separate the container glue flap 44 from the first partition panel glue flap 46. Since the previously glued strip 58 will adhere at 60 on the panel 14 the panel 50 and glue flaps 46, 54 will remain relatively stable on the panel 14. The wheel 62 will apply a glue strip 64 on the outer surface of the container glue flap 44. A glue wheel 66 will apply on the outer surface of the partition panel glue flap 54 a glue strip 68.

The next fold is made at fold line 20 and the side wall panel 12 will adhere to the glue strip 68 and the portion thereof adjacent the margin 70 will adhere to glue strip 64. When the container is erected in the manner shown in FIG. 6, the side wall panels 16 and 13 will swing in parallel relation about fold lines 20, 22 and 24, 38, respectively, and the partition panel 50 will be disposed parallel to panels 16 and 18 swinging about fold lines 48, 52 at the respective partition glue flaps 46, 54 secured on opposed inner surfaces of side wall panels 14 and 12, respectively.

As clearly seen in FIG. 7, when the side walls 12, 14 are parallel to each other, the side walls 16 and 18 will be disposed at right angles to the walls 12, 14 and parallel to partition 50 to form adjacent compartments X and Y in the erected container.

It will be noted that the blank 10 is substantially rectangular, thus there is practically no waste of material; the assembly of the container positively orients the partition panel 50 to form the compartments X and Y; the glue strips 58, 64 and 68 can be readily applied without requiring experience and involved apparatus and the cut line 46 is readily joined.

It will be obvious to those skilled in the art that various changes may be made without departing from the spirit of the invention and therefore the invention is not 3 limited to What is shown in the drawings and described in the specification but only as set forth in the appended claim.

We claim:
